BUTTON SETTiNG MACHINE.

SPECIFICATION forming part of Letters Patent No. 363,349, dated May 1'7,1887.

Application filed October 7, IP86. Serial No. 215,548.

the dotted line a at; Fig. 3, a vertical section 'of Fig. 1, taken onthe dotted line 3 y, also ,To all whom it may concern:

Be it known that 1, JOHN H. VINToN, of Boston, county of Suffolk, andState of Massachusetts, have invented an Improvement in Button-FasteningMachines, of which the following description, in connection with the accompanying drawings, is a specification, like letters onthe drawingsrepresenting like parts.

This invention has for its object to provide a button-setting machine ofthe class represented in United States Patent No. 812,987, granted to meFebruary 24, 1885, with suitable mechanism whereby the same may beoperated by power, and also with suitable clutch mechanism whereby onlyone staple and its attached button can be set by the setting tools ordevices at each time the main driving-shaft is engaged and rotated bythe cl uteh mechanism.

The invention consists of a cross-head and a button-setting tooloperated by its movement, and a crank or eccentric to move the saidcrosshead, combined with a driving-shaft for rotating the said-crank oreccentric, and a clutch mechanism mounted upon the driving-shaft forengaging the continuously-rotating drivewheel, to thereby rotate thesaid driving-shaft when desired, the said clutch mechanism being soconstructed and arranged that whenever moved into engagement with themain drivewheel it will there remain to rotate the main drive-shaft asufficient length of time to permit the button-setting tools or devicesto set one button only. I have in this instance loosely connected thetreadle-rod with the releasing device, by which the clutch is started orpermitted to engage the drive-wheel, so that when the said rod iselevated the releasing device acts to release the clutch, permitting itto engage the main drivewheel and to thereby rotate the drive-shaft, andimmediately after Fig. 2, a vertical section of Fig. 1, taken on (Nomodel.)

showing the standard and the frame supporting the machine; Fig. 4, alongitudinal section of the clutch, taken on the dotted line 2 2, Fig.3; and Figs. 5 and 6, details to be re ferred to.

The crosshead A, supported by the guide A,moving in a frame, A hasattached to it a buttoncarrier, A which cooperates with a stationaryanvil, A, the said buttoncarrier receiving one button and an attachedstaple from a raceway, A, at each time the buttoncarrier descends.

Suitable devices, consisting of a detent and let-oft attached to theraceway A and operated by projections attached to the moving cross-head,are provided to permit one button and attached staple to pass from thesaid raceway. i

The button setting machine herein shown is substantially such asrepresented and described in the United States Patent No. 312,987,beforelreferred to, andv to which reference may be had.

An arm, a, leading from the cross-head A, has an eccentric, a, mountedupon it, about which passes a strap, c of a pitman, a, the opposite endof the said pitman being connected with a crank, a, mounted upon themain drive-shaft 5, (see dotted lines, Fig. 2, and Figs. 4 and 5,) saidshaft having its hearings in suitable uprights, B 13, attached to anysuitable base or frame, 13

The main drive-wheel O is mounted upon the drive-shaft b, and afriction-collar, c, is also secured or keyed upon said shaft, againstwhich said drive-wheel C may be moved or brought under such frictionalcontact. as to cause the shaft b to rotate.

An abutting collar, D, or it may be, as herein shown, a hub madeintegral with the shaft 6, is located at that side of the drive-wheel Gop posite the friction-collar c, said abutting hub carrying twofriction-pawls, c which are slightly pointed, as shown in Fig. 5, sothat when lying parallel with the longitudinal axis of the shaft 6 thesaid points bear so firmly against the drive-wheel O as to force itagainst the friction-collar 0, but wl'len turned the ends of 5 slightlyon their pivots the said pawls permit the drive-wheel to turn freely.

The upper side of the pawls .0 (see Fig. 3)

is slabbed off to present two upwardly-inclined 5 surfaces meeting atthe longitudinal center to form a sharp edge or rib, which bearsfrictionally against the interior of a ring, 6, surrounding the hub D,the pawls being held in position by the flange c of the hub D, which Iis recessed for such purpose, as shown in Fig. 5.

A lug, 6, projects from the exterior of the ring e, which strikesagainst the end of a releasing device or lever, f, pivoted at f to aframe or support, J, said releasing-lever be- I ing held in suchposition by a spring, f, that the lug e maybear against it.

When the releasing device or lever f is moved sufficiently to permit thelug e to pass,

the ring a is started by the contraction of a' spring, g, (see Fig. 6,)one end of which is connected with a stud or projection, g, fixed to thering 0, and the other end to a stud or projection, fixed to the hub D.

The treadle-rod it passes upward through a hole or opening made-in thereleasing device f, the end of the said treadle-rod having a shoulder ornotch which is normally kept pressed against a holding-plate, n, by astud, it, acted upon by a spring, a a loose connect-ion being thus madebetween the releasinglever and the treadle-rod, so that as thetreadlerod is lifted the releasing-lever will be moved sufficiently torelease the lug e and permit the pulley O to take with it thedrive-shaft.

The treadlen'od'having been elevated far enough to lift the lever f andrelease the lug 6 the shoulder of the treadle-rod slips off the 7 platea, which permits the releasing-lever to resume its normal position,ready'to engage 4c the lug e as it completes its rotation with the ring.After starting the machine the treadlerod is quickly lowered toagain'engage the releasing-lever, as shown in Fig. 3, the ring 6 in saidfigure being shown as having completed about three fourths of itsrotation. The crank-disk a is cut away or notched,

as at a, (see Fig. 2,)-to be engaged by a suitable spring-controlledpawl or detent, a pivoted to the frame-work, the said pawl preventingbackward rotation of the shaft 1). As the said shaft 12 completes onerevolution the lug e will strike'the end of the releasinglever f, andthe momentum of the shaft carries it a little farther, sufficiently topermit the pawl a to engage the notch of the crank-wheel a and todistend the starting-spring g, said spring being thus held distended byengagement with the pawluntil the releasing-leverf is again moved topermit the lug e to pass when itcontracts, starting the ring e, and bythe frictional contact of the pawls 0 moves the said pawls intoengagement with the drive-. wheel 0, forcing the latter against thefrictioncollar 0 and thereby starting the drive-shaft.

It will thus be seen that each time the treadle- 6 5 bar is lifted theshaft 1) will make one complete revolution and no more, being checked bythe releasing-leverf, so that the cross-head A will be moved onlysufficiently to permit the button-setting tool or device to set onebutton.

I claim-- 1. In a button-setting machine, a cross-head andbutton-setting tools or devices operated by its movement, a crank oreccentric, and pitman for moving said cross-head, combined 7 5 with adriving-shaft for rotating said crank or eccentric, and aclutch-mechanism, substantlally as described, mounted upon thedrivingshaft for engaging a continuously-rotating drive-wheel to therebyrotate the said drivingshaft, and a releasing-device for permitting theclutch mechanism to rotate, and means, substantially as described, formoving said releasing device and permit it to resume its normalcondition, as set forth. 8

2. In a button-setting machine, the buttonsetting tools or devices,mechanism, as described, for operating them, the crank or eccentric formoving said mechanism, combined with a driving-shaft for rotating saidcrank or eccentric, and the clutch mechanism,substantially asdescribed,-mounted upon the driving shaft for engaging continuously therotating drive-wheel to thereby rotate the said drivinga shaft, and thereleasing-lever having a loose 5 connection with the treadle-rod bywhich the said releasing-lever is moved, as set forth.

3. In a button-setting machine, the buttonsetting tools or devices,mechanism, as described, for operating them, the notched crank oreccentric for moving said mechanism, and a pawl for entering the notchof said'crank or eccentric, combined .with a driving-shaft for rotatingsaid crank or eccentric anda clutch mechanism, substantially asdescribed, mounted upon the driving-shaft for engaging acontinuously-rotating drive-wheel to thereby rotate the saiddriving-shaft, and the releasinglever and treadle-rod normally inengagement with said releasing-lever, but constructed and :10 arranged,substantially as described, to disengage the releasing-lever whenrotated.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
